Robert De Niro and wife Grace Hightower are facing legal action from a former nanny who has accused the star couple of owing her more than $40,000 in overtime payments.

Former nanny Alexis Barry says,

“I went to work for the couple back in 2006 looking after thier son Elliot and they agreed to pay me $31.25 an hour and $46.88 per hour overtime.”

Barry has now filed papers in New York’s Manhattan Supreme Court claiming she clocked up 750 hours of overtime in her ten months working for the couple, but has not been paid for her extra service.

The lawsuit also claims that Barry never received 10 days of vacation time which she was promised, according to TMZ.com
